Shopping for cheap car insurance as an 18-year-old

The best strategy to find cheap auto insurance as an 18-year-old driver — or a driver of any age — is to shop around for rates at different insurers.

Insurers charge insurance quotes based on many factors, from the car you drive to your driving history. The company that offers you your best car insurance rate may be very different from those best suited for your peers or another 18-year-old who drives a van, pickup truck or high-performance sports car.

When shopping around for quotes, 18-year-olds, students and other young drivers, especially teenagers, can save by staying on their parents' car insurance policies or taking advantage of all available discounts.

To find affordable car insurance rates, 18-year-olds can …

  • Shop around. Insurance companies price higher rates for younger or more inexperienced drivers, but costs vary substantially across insurers. Some insurance companies charge lower premiums for younger drivers and teens compared to their peers. For 18-year-olds, we recommend Erie, USAA and GEICO where eligible, but the company best suited to your needs can vary.
  • Remain on a parent's policy. If you're a young driver, then staying on your parents' car insurance policy, when possible, can help you avoid typically higher premiums. A combined policy or multicar insurance policy may be more expensive for your parents than if you weren't included, but the total cost will be cheaper than that of two separate policies. If you're away from home at college or school for a good part of the year, your parents may be eligible for a "student away from home" discount that could offer them savings.
  • Take advantage of car insurance discounts. Insurers offer many discounts for which you may be eligible. These can reduce your car insurance price. An 18-year old driver, in particular, may qualify for car insurance deals and discounts by being a good student, passing a defensive driving course, having a good credit score or maintaining a clean driving record.


We collected car insurance quotes for thousands of ZIP codes across the 10 most populated states in the U.S. Our sample drivers were 18-year-old men and women who drove a 2015 Honda Civic EX. All other parameters affecting car insurance rates were consistent; drivers were single and had a clean driving record. Coverage levels in the full coverage policy, including liability insurance, are listed below. These coverage levels are slightly higher than any individual state's minimum coverage requirements:

Coverage typeStudy limits
Bodily injury liability$50,000 per person/$100,000 per accident
Property damage$25,000 per accident
Uninsured/underinsured motorist bodily injury$50,000 per person/$100,000 per accident
Comprehensive and collision$500 deductible
Personal injury protection (PIP)Minimum when required by state

The analysis included 23 insurance companies, though rates were only added to our list of average prices and recommendations if their policies were available in at least three of the 10 states.
